Inadvertent actuation block valve for a small modular nuclear reactor
An inadvertent actuation block valve includes inlet and outlet orifices being in selective fluid communication via a chamber. A disc is disposed within the chamber and a bellows is configured to contract at a predetermined pressure differential between reactor fluid entering a reference pressure orifice and control fluid entering the inlet orifice. When the bellows contracts, the disc engages the outlet orifice and isolates fluid communication between the inlet and outlet orifices. The inadvertent actuation block valve prevents inadvertent opening of an emergency core cooling valve when a reactor is at operating pressure that is above the predetermined set pressure range. The inadvertent actuation block valve permits the emergency cooling valves to open and to remain open when reactor pressure is below the predetermined set pressure range. The inadvertent actuation block valve does not impede long term emergency cooling that occurs when the reactor is at low pressure.

The present invention extends to an electric actuator for operating an unheading valve of a coke drum. The electric actuator includes a driving element comprising a planetary roller screw for actuating the unheading valve. By using a planetary roller screw, rather than hydraulics for the driving element, the electric actuator of the present invention can be used in place of prior art hydraulic actuators while still providing sufficient power and reliability for use on unheading valves of a coke drum.
The present invention extends to a center feed system that allows residual byproduct to be injected into a vessel from within the center of the vessel. The center feed system can include an inlet sleeve that is attached to the vessel and a retractable injection nozzle that extends into the vessel to inject residual byproduct into the vessel and that retracts into the inlet sleeve after injecting the residual byproduct. A retractable injection nozzle in accordance with one or more embodiments of the invention may include one or more openings that each includes an insert that can be removed from the opening. The inserts can therefore be replaced to customize the functionality of the nozzle or to replace the inserts when they have become worn.
A seat system for a coke drum deheading valve can include a groove in the surface of the seat for supplying a lubricant to the surface of the seat. Various channels can be formed in the body of the seat that connect to the groove. In this way, lubricant can be flowed through the channels and into the groove to provide lubrication between the surface of the seat and the blind. The seat system can also include a split ring packing gland to facilitate the formation of a seal within the deheading valve. The split ring packing gland can be used to retain and compress packing positioned between a retaining ring and a dynamic seat such that when the packing is compressed, an improved seal is formed. By improving the seal, less steam can be required during the delayed coking process thereby increasing the efficiency of the system.

A coke drum skirt to minimize the stresses experienced by the coke drum and the supporting structure of the coke drum is described. The skirt includes one circumferential horizontal plate attached to the coke drum, and the circumferential horizontal plate is slidingly sandwiched between a lower supporting plate that supports the weight of the drum through the circumferential horizontal plate and an upper retaining plate that prevents the coke drum from tipping or falling over. The upper retaining plate may be embodied as a series of retaining clips that also keep the coke drum centered and prevent rotation of the coke drum. The upper and lower plates are anchored to a concrete support base. The sliding connection of the plates allows the coke drum to thermally expand and contract while reducing stresses and metal fatigue from the typical fixed securing of the coke drum to the support base.

A Stall Warning System (SWS) utilizing the detection and analysis of stress waves, (i.e., ultrasound) emitted by combustion and/or turbulent flow processes of an apparatus, such as a turbine engine, for example. Upon detection of an impending stall condition, the SWS can inform the operator, inform another electronic device (computer, etc.) and/or latch the event for review by maintenance personnel.
A statistical process, and system for implementing the process, is described for the analysis of stress waves generated in operating machinery or equipment. This technique is called Probabilistic Stress Wave Analysis. The process is applied to a population of individual “feature” values extracted from a digitized time waveform (such as a 2 second Stress Wave Pulse Train, or a 2 month history of Stress Wave Energy). Certain numeric descriptors of the statistical distributions of computed features are then employed as inputs to decision making routines (such as neural networks or simple threshold testing) to accurately classify the condition represented by the original time waveform data, and thereby determine a status of the operating machine/equipment.

The present invention relates to a vibration monitoring device and methods for using the same. Specifically, the invention relates to a vibration monitoring device which may be utilized throughout a delayed coker unit operation to ascertain whether the cutting tool is boring, cutting or ramping mode.
A system allows an operator to remotely switch between cutting and boring while removing solid carbonaceous residue from large cylindrical vessels called coke drums. The system comprises a cutting head for ejecting high pressure fluids into the coke bed; a flow diversion apparatus; and a shifting apparatus. A drill stem allows for the movement of fluids through the interior of the drill stem to a cutting tool. High pressure fluids can flow through the stem to cutting tool the cutting nozzles and out through boring nozzles or cutting nozzles.
